Attorney General Jeff Sessions became flustered under questioning from Democratic Sen. Kamala Harris during a Senate Intelligence Committee hearing on Tuesday concerning his communications with Russians, President Donald Trump, and Trump’s aides during the presidential campaign.

Soon afterwards, the senator tweeted two of the questions she posed to Sessions:
